Seasteading: Libertarians dream of creating self-ruling floating cities. But can the many obstacles, not least the engineering ones, be overcome?
Dec 3rd 2011 | from the print edition
THE Pilgrims who set out from England on the Mayflower to escape an intolerant, over-mighty government and build a new society were lucky to find plenty of land in the New World on which to build it. Some modern libertarians, such as Peter Thiel, one of the founders of PayPal, dream of setting sail once more to found colonies of like-minded souls. By now, however, all the land on Earth has been claimed by the governments they seek to escape. So, they conclude, they must build new cities on the high seas, known as seasteads.
It is not a completely crazy idea: large maritime structures that resemble seasteads already exist, after all. Giant cruise liners host thousands of guests on lengthy voyages in luxurious surroundings. Offshore oil platforms provide floating accommodation for hundreds of workers amid harsh weather and high waves. Then there is the Principality of Sealand, a concrete sea fort constructed off Britain’s coast during the second world war. It is now occupied by a family who have fought various lawsuits to try to get it recognised as a sovereign state.
Each of these examples, however, falls some way short of the permanent, self-governing and radically innovative ocean-based colonies imagined by the seasteaders. To realise their dream they must overcome some tricky technical, legal and cultural problems. They must work out how to build seasteads in the first place; find a way to escape the legal shackles of sovereign states; and give people sufficient reason to move in. With financing from Mr Thiel and others, a think-tank called the Seasteading Institute (TSI) has been sponsoring studies on possible plans for ocean-based structures and on the legal and financial questions they raise. And although true seasteads may still be a distant dream, the seasteading movement is producing some novel ideas for ocean-based businesses that could act as stepping stones towards their ultimate goal.
Floating some ideas
Seastead designs tend to fall into one of three categories: ship-shaped structures, barge-like structures based on floating pontoons and platforms mounted on semi-submersible columns, like offshore oil installations. Over-ordering by cruise lines means there are plenty of big, second-hand liners going cheap.
Ship-shaped structures can pack in more apartments and office space for a given cost than the other two types of design, but they have a big drawback: their tendency to roll in choppy seas. Cruise ships can sail around storms, but static seasteads need to be able to ride them out. And the stabilisers on big cruisers only work in moderate seas and when the ship is moving.
